WINDMILL.

SPECIFICATION forming part of Letters Patent No. 353,721, dated December 7,1886.

Application filed April 5, 1886.

To all whom it may concern.-

Be it known that We, GEORGE \VALLENBECK and EDWARD \VALLENBECK, citizens of the United States, residing at Villow Creek, in

5 the county of Tompkins and State of New York, have invented certain new and useful Improvements in Windmills; and we do declare the following to be a full, clear, and exact description of the invention, such as 1 will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this I specification, in which- Figure 1 is a viewin perspective, with parts broken away. Fig. 2 is a detail view showing the manner of operating the rotating shaft. Fig. 3 is a sectional view showing the peculiar 2 construction of the turn-table. Fig. 4 is a detail view showing the operation of the wheel 0 and crank-pin V in connection with the groove in the flange D.

Similar letters of reference indicate corresponding parts in all the figures.

Our invention has relation to windmills, and it contemplates certain new and useful improvements therein; and it consists, to that end, in the improved construction and combination in parts of the same, as hereinafter more fully described and claimed.

A is a spider, to which the ordinary propelling-wheel is attached. This spider is secured to the main shaft B by means of a set-screw.

3 5 The cog-wheel O is mounted on the main shaft B, and firmly secured thereto by means of a set-screw.

D is a metal flange, firmly attached to the hollow rod E at the point I). In this flange,

0 on the side next to the wheel G, is a horizontal slot large enough to receive the head of a crank-pin, which is firmly attached to the wheel 0 at the point a, which moves readily in the horizontal slot.

To the hollow rod E, at its lower extremity, is fastened, by means of the spool-joint, the curved iron G, looping around the spool so as to turn easily thereon. To this iron is bolted the pump-stroke H, made either of wood or metal. I

To the casting I there is fastened, by means of bolts and nuts, the stub-axle K. Revolving 011 this axle is a cog-wheel, L, similar in all respects to the cog-wheel C, and so adjusted that the cogs in said wheel engage the cogs in wheel 0.

Firmly attached to the rod N is the metal flange M, similar in all respects to the flange D, having a horizontal slot,whicli receives the head of a crank-pin firmly attached to cog- A wheel L, said crank-pin working back and forth in said slot. The rod N extends downward through the hollow rod E, and has at its lower extremity, attached loosely by means of a spool-joint, the curved iron 0. To this iron is bolted the wooden or metal pumpstroke P. In each of these pump strokes there is set and rigidly secured, by means of bolts, the metal casting Q Q, shaped as in Fig. 2, containing vertical slots 0 c and horizontal slots at d.

Encircling the hollow rod E is the spool 6, moving easily up or down on said rod. Two curvedirons,f loop loosely around thespool. At the lower end of the iron f and extending downward is a wooden rod, h, which is used as 7 5 a handle. Around the rodg there is bent and rigidly secured the piece of metal t, containing a small circular opening, into which the short rod is is hooked.

To the vane'arm R at the point bis pivoted the bent lever S, having a long arm, m, and a short arm, n, containing each circular openings, by means of which the lower end of rod kis hooked into the arm n, and one end of the rod 0 is hooked into the long arm m. E

To the vanearm R is permanently fixed the bent iron rod p. Around this is looped loosely the iron rod q, bent and extending, as shown in the figure. the other end being attached to the V-shaped iron 2', rigidly secured to the frame.

To the rod q, at or near the point of bending, is attached the transverse rod 8, having at each end fans a, which are at right angles to the vane and to the direction of the wind. 5 Around the rod q, and between the rods 1) and s, the rod 0 loops.

Fig. 3 shows a sectional view of the antifriction turn-table.

a is a cylinder, the sides of which are con- I00 cave, forming segments of a semicircle, looking outward, large enough to receive half of one of the anti-friction balls b.

is a'metal casing firmly bolted to the mast. 5 This casing is concave, as shown inV, Fig. 3,

the'concave surfacelooking inward and forming,with the concave surface of the cylinder a, a circular groove extending around the cy1inder to receive the anti-friction balls I).

d is a triangular-shaped piece of metal, as shown in Fig. 2, having pins 6 e on each side, pointing in opposite directions. At equal distances from the pins 6 e, in the third corner of the triangular-shaped piece of metal,(the pins 1 5 e e Leing placed in each of the other corners,) is

a circular opening, through which the rotating axle f passes, and in which it is rigidly secured. 1

g'g"are oblong slides, made either of wood or metal, provided attheir central points with circular openings large enough to receive the pins 6 e and allow said pins to turn easily therein. The slides g and g are made so as to move back and forth in the horizontal slots at and d 2 5 in the castings Q Q.

i The operation of our mill is as follows: When the propelling-wheel revolves, the main shaft, on which is mounted the cog-wheel G,

turns, thereby rotating said wheel. The cogs of 0 this wheel engaging the cogs in wheel L, causes that wheel to revolve in an opposite direction. When the wheel 0 revolves, the crank-pin on the wheel, bearing in the horizontal slot in the metal piece D, rigidly attached to the hollow rod E, causes said rod to rise and fall. The

crank-pin on the wheel L, bearing and work- .ing in the horizontal slot in the metal piece M, firmly attached to the rod N, passing through the hollow rod E, causes the rod N to. 0 rise and fall in a direction opposite to that of tlius bearing down on the spool e, to which is,

= attached the rod 9. This pushes on rod is,

which causes the bent lever S to turn on its pivct b, which pushes out the rod q, sliding on rod 2, This pulls'on rod g, which, acting on the frame by means of the V-shaped iron r, 5 causesit to revolve on the turn-table until the propelling-wheel is parallel to the vane and to the direction of the wind, when the mill is out of gear. This operation is aided by the fans a at each end of rod 8. By reversing the to above the mill may be started.

The operation of the turn-table is amply shown in Fig. .3. All the weight is directly on the cylinder a,- but the cylinder rests on the anti-friction balls b, and the weight falls on said balls obliquely, (instead of directly,

as in the ordinary construction,) thus reducing friction to a minimum.

The rotating shaft is operated asfollows: When. the pump-stroke P is at its highest point, the slide 9 rests at the center of the slot d and immediately over the axle f, making a deadpoint. At the same time the pumpstroke H has passed up through half its distance and the slide g rests at the extremity of p the slot d, and from this position the pumpstroke H, continuing to ascend, overcomes the dead-point in the slide 9, starts the pump stroke P to descend, and reaches its own deadpoint. When the pump-stroke P has in its descent reached within half its limit and its it overcomes the dead-point in the pump .stroke H. The slides g 9", attached to the triangular piece d, in which is mounted the axle f, cause said axle to revolve, and the two, pump-strokes, moving reciprocally, relieve the dead-centers of each other, and thereby convert their vertical motion into the rotary motionof the shaft f.

Having described our invention, we claim 1. The combination, with two slotted recip- ,IOcating pump-strokes provided with guides at right angles to the bars, and slides in said guides, of a shaft passing through the slots of said bars and provided with two crank-arms attached to the shaft at about right angles to each other and engaging the slides in the guides in the reciprocating bars, substantially as described.
